Coming off a 15-2 season, the Lions know they have a championship window. Keeping key free agents could help keep that window open a little bit longer. Here are a few free agents the Lions need to consider keeping in 2025.

Detroit Lions guard Kevin Zeitler (71) warms up before the game between Detroit Lions and Minnesota Vikings at Ford Field in Detroit on Sunday, Jan. 5, 2025.

CB Carlton Davis

Davis was essentially on a one-year “prove it” deal with the Lions after he was acquired via trade with the Buccaneers and he more than proved his worth, helping turn a unit that was a weakness in 2023 into a strength in 2024. Davis recorded 56 tackles and two interceptions in 13 games before a broken jaw ended his season.

DL Levi Onwuzurike

Onwuzurike provided quality play up front for the Lions with 28 tackles, 1.5 sacks and 37 quarterback pressures, helping the unit stay afloat after the injury to Alim McNeill. The Lions need to refill their depth behind McNeill and DJ Reader and that should start with Onwuzurike.

OG Kevin Zeitler

Zeitler will be 34 years old but, like Davis, was a huge free-agent pickup this season, being not only one of the top offensive linemen for the Lions but one of the best offensive linemen in the entire league. Zeitler graded as the 3rd-best offensive guard by Pro Football Focus, behind only Chris Lindstrom (Falcons) and Quinn Meinerz (Broncos). Even if it’s a one-year deal, Zeitler helps keep the offense intact and will keep opening holes for Jahmyr Gibbs and David Montgomery.

CB Kindle Vildor

The Lions will also need depth behind Davis, Terrion Arnold and Amik Robertson. Vildor was very serviceable when he was needed to fill in due to injuries. He had a pass defended, one of only two in the game, against the Commanders in the Divisional Round. He can be brought back as an extra body next season.
